User did a batch update to change the project status in Core, but had phased projects that were not expanded at the time. This action did not update the project status of the phases.
To update the projects as well as its phases, you must expand the list of phases and check each one of them before performing a batch update on them. You have to select the phases individually only if the parent project type is Standard. However, if you the parent project type is Main, then all the phases below are selected automatically with the parent project selection when doing a batch update.
